To all whom it may concern: 7

Be it known that ll, LEONARD LOOP, a citizen of the United States, residing at ()kmulgee, in the county of Okmulgee and State of Oklahoma, have invented a new and useful Deep-Well Pump, of which the following is a specification.

The present invention appertains to pumps for extracting oil and other liquids from deep or Artesian wells.

One of the objects of the present invention is to provide a novel valve for a deep well pump, which is designed for preventing the particles of sand and other foreign matter within the well tubing or casing from settling or precipitating back or downwardly to the piston and check valve, especially when the pump is idle, and to thereby prevent the piston from becoming clogged or stuck within the pump barrel, and to also prevent the barrel and piston from being scratched and worn due to the presence of sand and other extraneous matter.

Another object of the invention, is to provide in combination with the sand valve, of novel means for driving the same home within the pump, and whereby the piston may be actuated for driving the check valve home as usual.

It is also within the scope of the invention, to provide a sand valve structure and driving means therefor which will be comparatively simple and inexpensive in construction, which may be readily assembled with the prevailing types of deep well pumps, and which will be thoroughly practical and efiicient in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed,- it being understood that changes in the precise embodiment of the invention herein disclosed can be made with? in the scope of what is claimed without departing from th'espirit of'the'invention.

The invention is illustrated in its preferred embodiment in the accompanying drawings, wherein Figure 1 is a vertical central section through the pump structure, illustrating the present improvements applied thereto.

Figs. 2 and 3 are enlarged cross sections taken on the lines 2-2 and 3-3, respectively, of Fig. 1.

In the drawing there is illustrated an ordinary pump barrel 1 which is connected by means of the coupling or union 2 to the lower end of the well tubing or casing 3, a common check valve 4 being disposed within the lower end of the barrel 1 and be ing adapted to be driven into the coupling or nipple 5 threaded uponthe lower end of the barrel. 7 The usual piston 6 is slidable within the barrel 1 and is provided with a valve for enabling the oil or other liquid to pass upwardly through the piston when the piston is depressed. The piston 6 is pro-videdwith an upwardly projecting piston rod 7 extending through the coupling or union 2 into the lower portion of the well tubing 3.

In carrying out the present invention, the upper end of the pump barrel 1 is tapered, as at 8, to receive the lower tapered end of an annular valve seat 9 mounted upon the piston rod 7 within the coupling 2. The

annular valve seat 9 isprovided with an.

annular series of vertical bores or passages 10 therethrough.

- The valve seat 9 is provided with an upstanding neck 11 surrounding the piston rod 7 and provided at its upper end with a head 12 having an upstanding tongue 13 of arcuate cross section and fitting against one side of the piston rodjZ.

The head or coupling member 14 is threaded upon the upper end of the piston rod 7, and is provided with an upstanding threaded stub 15 for the engagement of the usual pump rod 16 which extends upwardly through the Well tubing 3 to the actuating mechanism (not shown). The head 14 is provided wit-h a depending tongue 17 of arcuate cross section and: snugly fitting one side of the piston rod 7"to complement the tongue 13.

An annular valve 18 is mounted slidably upon the neck 11' between the valve seat 9 and the head12, and is normally seatable upon the seat 9 over the passages 10, to serve as a check valve for supporting the column or head of oil or other liquid with in the well tubing 3.

In the ordinary operation of the pump,

carried thereby lor the usual pumping operation.

The cardinal feature of the invention resides in the fact that when the oil or other liquid is forced upwardly by the piston, the oil will beforced through the passages 10 of thevalve seat 9, to raise the valve 18, and'when the piston moves downwardly or is idle,the valve 18 will be seated, to not only support the column of liquid within the well tubing, but also to prevent the settling or precipitation of sand or other foreign matter from within the well tubing down into the pump barrel 1, which not infrequently results in the clogging or sticking of the piston, or the scratching or marring of thepis ton and pump barrel. Considerable trouble is experienced in practice, especially after the the pump has'been idle for a period of time, in the accumulation of sand within the pump barrel, due to the factthat the sand will precipitate downwardly to the piston. IVith the present sand valve structure, however, these objections are eliminated. In this connection it is to be understood that the oil which is pumped by the deep well pumps is usually extracted from sand rock or similar strata, which results in particles of sand or other foreign matter being drawn or sucked into the pump barrel and tubing, which in precipitating is injurious to the leather cups or packings of the piston and check valve.

The present appliance also embodies means for driving the sand valve seat 9 home, and for enabling the check valve L to be driven home in the usual manner. Thus, when the pump rod 16 is lowered and swung properly to enable the tongue 17 to overlap the tongue '13, as-seen in nig. 1, the pump rod may be reciprocated for causing the piston 6 to impinge against the check valve structure l to drive the check valve structure tightly into place ,so that it will not be dislodged during the operation of the pump. Then the pump rod is lowered to the limit, the interengageable means of the piston and check valve structure l are arranged to be interlocked by a turning movement of the pump rod 16 in the usual manner, and the tongues 17 and 13 being overlapped will cause the piston rod 7 to turn with the pump rod, and at the same time, the valve seat 9 Willbe turned with the tongue 13 and its head 12. After the check valve 4: has been driven home, the valve seat 9 may be driven tightly into place within the tapered portion 8 ofthe well barrel 1, and to this end, the pump rod 16 is lifted sufliciently and then turned to enable the tongue 17 to impinge or seat upon the upper end of the tongue 13, which will enable the valve seat 9 to be forced downwardly. Thus, by reciprocating the pump rod 16, the tongue 17 may be forcibly struck against the tongue 13 carried by the valve seat 9 to drive the valve seat into place. Then, by further raising the pump rod, the pumping operation may take place without interference. In removing the parts from the barrel, the piston 6 may be lowered to catch onto the check valve structure I, and then by raising the piston, it will lift the sand valve structure therewith, as will be apparent.
